This document specifies minimum requirements and test methods for elastomeric seismic isolators
used for buildings and the rubber material used in the manufacture of such isolators.
It is applicable to elastomeric seismic isolators used to provide buildings with protection from
earthquake damage. The isolators covered consist of alternate elastomeric layers and reinforcing steel
plates. They are placed between a superstructure and its substructure to provide both flexibility for
decoupling structural systems from ground motion, and damping capability to reduce displacement
at the isolation interface and the transmission of energy from the ground into the structure at the
isolation frequency.
